There doesn't seem to be a damn bit of level ground around the outside of my house, which makes climbing a ladder a truly frightening experience. I could definitely use something like Feet First.
The device attaches to each side of the ladder and helps improve traction and level control with feet that are fully adjustable. I'm surprised something like this doesn't already exist—but I wouldn't be surprised if that changed sometime in the near future. [Tuvie]
